Our DIY solar photovoltaic KITS, sold all over the world, are the cheapest way to provide energy by the sun and are perfect for project so-called "isolated","stand-alone","off-grid" which are isolated by different energetic source such as nation's electrical grid;the scope of such use are several, for example craft, caravan or camping, gardening,lighting, small electrical household appliances, electronics and so forth.

Our kits of DIY solar panels are the cheapest way to provide electricity from the sun and are perfect for stand-alone installations, which is isolated from other energy sources such as the national grid; usage applications are many, such as boats, mobile homes or camping in general, garden lights lighting, small appliances, electronics and much more.

Building panels is highly educational and fun, they are also versatile in that you can customize voltage / current / dimensions to suit your needs, something not possible with pre-assembled solar panels.

If you are a beginner and want to learn more about the cells and tips on how to make the welds and all the components you need, you can read our articles in the Learning Zone or watch video tutorials in our youtube page that exaplains best practices to soldering solar photovoltaic cells.

We always add some cells to compensate the breaks during welding or during transportation, in any case for any problem due to sending please contact us and we will do our best to solve all your problems, because the important thing for us it is that you remain 100% satisfied.


In all PV systems Island (then with batteries), it is essential the use of charge controllers to prevent overcharging of batteries that are not too rare cases can cause the explosion of the battery (see electrolysis).

It will be very important to mount the solar cells efficiently to ensure long life of the panel, low risk of corrosion and cracking. There are several options to achieve a good result like the encapsulation of cells within a double glazed window, the use of silicone resins as special QSIL 216 or use sheets of EVA to name just a few examples. In the Learning Zone of our website you can find other more economical methods to achieve a good result.

It is also advisable to use a soldering iron of 60W - 80W and no less powerful with flat point. You must also have the cells on a smooth surface of glass or other thermally insulating materials.
